According to one known process a chocolate beverage ismadei by heating a mixture of water and ground cocoa, or a mixture of water and chocolate instead, whereby the 5 starch constituents of the cocoa become pasty; the pasty-starch is y any of the known means and thecooled then saccharified liquid is separated from the fat particles and insoluble constituents. After the'sac'pharificatio of the starch the liquid may also be yeast fermentation and the clear liquid then'separated from the fat and the insoluble constituents. The product is a clear liquid which does not deposit. Aless bothersomeprocess is also known in which-invert sugar 'syrupof particular- -composition is mixed with cocoa and this mixture is brougli tv either nearly or complete- 7 1y to the boiling temperature for a. shorter orlonger time. By means of this process a chocolate materiaL-of paste-like quality is'ob- I I I tained. The process cannot be' employed to make a homogeneous chocolate mixtur which deposits no sediment.

contradistinction to these known processes, aconcentrated food substance is made by the new process forming the subject of this invention, from cocoa, sugar and water by heating the constituents, in such a Its manner thatcocoa. powder together with the aqueous solution of sugar is broken down with addition of acid, e. g. formic acid. The disintegration or breaking down process. extends both to the starch as well as to the protein substances of the cocoa. In consequence aqueous liquid the insolubleconstituents are brought mto a state of sus ension, in which they remain even on long eeping; even when kept for a longtime no solid sediment forms in the storage vessels.

In its simplest Thirty to parts of suganaredissolved in about 40 parts of water and 20 partsof cocoapowder from'which the oilhas'been removed and, if necessary 5 to 10 parts of wheatflour as well, are added thereto; the addition of some acid, fruit acid, or even by lies or oxide of lime, form th new process is as ifirst of addition of a suitable mineral acid, such as f phosphoric acid, or a mixture of such organic acidsand mineralacids, which maybe constituents of a food substance, and heated to about boiling'temperature. The heating is continued until the protein substances present in the mixture are converted to a considerable extent by partial degradation into a .favourable state of swelling in the liquid which is rich in soluble constituents (sugar) which prevents the deposition ofthe insoluble parts of the mixture. Soluble mineral salts may also be added to well in the acidified aqueous liquid. The colloidal solution of the albumin substances in combination with the content of soluble substances in the liquid enablesa state of suspension of the insoluble particles of the mixall time, which particles are'softened by the heating in the acidified liquid and swollen. One can also prociedby first ofall dissolving the sugar-(sa charose). in water and heatin and inverting in presence of acid; after t e-"sugar has inverted to a suflicient extent the powder-like food substances are'introduced into the liquid and the mixture then further heated as stated above.

A paste or suspension of milk powder may be added .to the mixture made according to the described process, if necessary before the boiling'process servingfor attaining the full effect aimedat is stopped. After intimate admixture of the two liquids the mixture is subjected,to raised pressure and. temperature such that casein .and albumin substances go into solutionfrom the milk powder and a liquid preparation is obtained-inwhich neither the cocoa constituents nor the milk. constituents form a sediment. even'lafter a long time.

The pasteor suspension of the milk powder in water, which may be made. from skimmed milk powder'or full milk powder, or else the mixtureof the suspension or paste of the milk powder with the l'cocoa-su'gar time is homogenized by means of any of the known devices suitable he'refor prior to the last heating which takes place under raised pressure.

Cocoa paste may also be used insteadof. cocoa powder "for makingthis concentrated chocolate milk.

On'mixing with water a nutrient beverage of agreeable taste is obtained which may be consumed preferably warm in winter, but also cold in summer.

{A process s already known for making cocoa milk inwhich the non-soluble constitufe'nts ofthe. cocoa are maintained in suspension in the liquid by partlcular means for a limited time-about 24 hours. The milk or the mixture of milk with the, cocoa is heated under pressure for a exceed acertain natural in other ways is also also already" been proposed to homogenize such mixtures by means of the known devices. In contradistinction' thereto, in the present process; the mixture of cocoa, sugar and water the constituents of the cocoa, more particularly the protein substances are broken down to such an extent that the insoluble constituentsof the mixture no longer form solid sedi- Firstthev preparation so obtained is mixed with the milk constituents and heated, and thereupon the-acid content of the already prepared oodefinite period; the milk coa-sugar preparation is used to convert the protein substances of the milk into a state of :swelling as well up to a certain extent.

What I claim is:
